Pros
The problem with large companies as an engineer is that you rarely get a say in what areas of technology you want to explore or learn about. If the company has standardized on Java then you are pretty much hosed. The plus side about working at a smaller company is you get to explore and grow without a large amount of the bureaucracy you'd find at a much larger company. Dishcrawl tends to adopt a solution first strategy. Python is mostly used but it doesn't mean we frown on PHP. Whatever gets the job done. As with a lot of startups there is a good deal of autonomy with a focus on the end result.
Cons
It is a lot of work. There is an infinite amount of things you can make and picking what direction to go is tough. Like with all code there are bugs and critical ones have to be fixed quickly (even if it is 9pm on a Sunday night).
